Cannot compile code that contains ISR() macro

[Warwolt]

I tried writing a sketch that contained

ISR(TIMER1_COMPA_vect)
{
    digitalWrite(13, HIGH);
}

When I compile this using the Arduino IDE, it works fine and I can flash and run the code. If I try to compile this inside Sublime 3 using Stino, I get an error like this:

[Build] C:/Users/rasmu/Documents/Arduino/led_pong...
[Step 1] Check Toolchain.
[Step 2] Find all source files.
[Step 3] Start building.

C:/.../led_pong/led_pong.ino:19:6: note: previous declaration with 'C++' linkage
 void setup()

Something seems to be happening with the preprocessing of the ISR() macro?

I can confirm that I have this exact same behavior on OSX. I have been able to work around it by placing extern "C" { and } around my ISRs. Its pretty obnoxious, but it seems to compile in both Stino and the regular Arduino IDE.

I am facing the same issue. The following example compiles on arduino IDE but with stino I get the error "error: conflicting declaration of 'void __vector_11()' with 'C' linkage" also the extern "C" {} does not work any help??

boolean blink;
void setup()
{
  // put your setup code here, to run once:
  Serial.begin(9600);
  initMyTimer();
}

void loop()
{
  // put your main code here, to run repeatedly:
  delay(1000);
}

void initMyTimer(void)
{
  noInterrupts(); // disable all interrupts
  TCCR1A = 0;
  TCCR1B = 0;
  TCNT1 = 0;
  OCR1A = 250; // compare match register 16MHz/64/250 results in 1ms/Tick
  TCCR1B |= (1 << WGM12); // CTC mode
  TCCR1B |= (1 << CS11); // 64 prescaler
  TCCR1B |= (1 << CS10);
  TIMSK1 |= (1 << OCIE1A); // enable timer compare interrupt
  // timer 2 for custom PWM
  interrupts(); // enable all interrupts
}

ISR(TIMER1_COMPA_vect)
{
  // timer compare interrupt service routine
  static unsigned int OneSecTimer = 1000;
  if (OneSecTimer > 0)
  {
    OneSecTimer--;
  }
  else
  {
    OneSecTimer = 1000;
    blink = !blink;
    Serial.println("tick");
  }
}

Finally I managed to compile it using the code (separate declaration of ISR...):

boolean blink;
void setup()
{
  // put your setup code here, to run once:
  Serial.begin(9600);
  initMyTimer();
}

void loop()
{
  // put your main code here, to run repeatedly:
  delay(1000);
}

void initMyTimer(void)
{
  noInterrupts(); // disable all interrupts
  TCCR1A = 0;
  TCCR1B = 0;
  TCNT1 = 0;
  OCR1A = 250; // compare match register 16MHz/64/250 results in 1ms/Tick
  TCCR1B |= (1 << WGM12); // CTC mode
  TCCR1B |= (1 << CS11); // 64 prescaler
  TCCR1B |= (1 << CS10);
  TIMSK1 |= (1 << OCIE1A); // enable timer compare interrupt
  // timer 2 for custom PWM
  interrupts(); // enable all interrupts
}
extern "C" ISR(ISR(TIMER1_COMPA_vect));

ISR(TIMER1_COMPA_vect)
{
  // timer compare interrupt service routine
  static unsigned int OneSecTimer = 1000;
  if (OneSecTimer > 0)
  {
    OneSecTimer--;
  }
  else
  {
    OneSecTimer = 1000;
    blink = !blink;
    Serial.println("tick");
  }
}

This has saved me. I want to share my simple code in here which make sublime have a hard time compiling by giving the error: conflicting declaration of 'void __vector_11()' with 'C' linkage ISR(TIMER1_COMPA_vect)

int timerCounter1;
int timerCounter2;
void setup()
{
    pinMode(13, OUTPUT);
    initMyTimer();
}

void loop()
{
}

void initMyTimer(void)
{
    // ------------------------------------------------------------------------------------------------------
    // TIMER INTERRUPT SETUP
    // ------------------------------------------------------------------------------------------------------
    // initialize Timer1
    cli(); // disable global interrupts
    TCCR1A = 0; // set entire TCCR1A register to 0
    TCCR1B = 0; // same for TCCR1B
    // set compare match register to desired timer count: every 0.100032 ms
    OCR1A = 1562;
    // turn on CTC mode:
    TCCR1B |= (1 << WGM12);
    // Set CS10 and CS12 bits for 1024 prescaler:
    TCCR1B |= (1 << CS10);
    TCCR1B |= (1 << CS12);
    // enable timer compare interrupt:
    TIMSK1 |= (1 << OCIE1A);
    sei(); // enable global interrupts
}

extern "C"
{
    ISR(TIMER1_COMPA_vect)
    {
        timerCounter1++;
        timerCounter2++;
        if (timerCounter1 == 30)
        // LIGHT ON @ 3000
        {
            digitalWrite(13, HIGH);
        }
        else
            if (timerCounter1 ==40)
            // LIGHT OFF @ 3400
            {
                digitalWrite(13, LOW);
                timerCounter1 = 0;
            }
    }
}
